Lots of orchids are epiphytes, with their roots twining round the bark, their layered leaves building up, and the flowering stem pointing in any direction (up towards the light, sideways, even down, especially when mature and load-bearing with buds and blossom).
Some people try to move their orchids into a more natural position and use a hanging basket like this:

That way, you can still put it near the window (freeing shelf space) and relieving the boughs by letting them dangle. A healthy plant’s stem won’t break that way. Furthermore, the aerial roots expose more surface area to catch humidity from the ambient air. Also, you can use a wire or thread (anchored at the top hook) to suspend the beam to your needs.
If you prefer leaving it in its pot, keep looking for a larger pot (> 20 cm seems to be rare) to have a firm balance point, and use climbing aids or small trellises like this one or that one. You can also build one yourself, so material and shape blend in with your surroundings. With it, you easily support the flowering stem while maintaining control of the direction of growth.
